Follow-up Comment #5, bug #41234 (project octave):

hmmm ... maybe?

It should only be:
add variable to track if need delete file, and protect:

# keep track of if need to delete a tmp file
delete_file = false;

Attempt to get the the file with urlwrite if couldnt find it locally (where it
was reporting couldnt find the file).

[fn, status, msg] = urlwrite (filename, tmpnam ());
if (! status)
  error ("imread: cannot find or download %s", filename);
delete_file = true;

And the cleanup at the end of the function:

  if (delete_file)
    unlink (fn);

And some changes in the indenting because of the unwind_protect block.

In the version I was looking at, there wasnt any shared code for that section
of the changes - but I did base my changes on what imfinfo was doing.
